ADDITIONS TO THE FLORA OF ALDERNEY. 



BY MR. E. D. MARQUAND, A.L.S., EX-PRESIDENT. 



A considerable number of unrecorded plants have been 

 discovered in Alderney during the past two summers, and as 

 some of these are new to the Channel Islands, I think it well 

 to note them without further delay, as a first supplement to 

 the Flora of Guernsey. 



Probably the most interesting plant that has yet been 

 found in Alderney is Isoetes Hystrix, which it was my good 

 fortune to discover last May. It grows in profusion on one 

 part of the cliffs, a little east of La Quoire, at an elevation of 

 some 150 to 200 feet above the sea ; but I have not as yet 

 detected it anywhere else in the island. It may be remembered 

 that Isoetes was not known to occur anywhere in Europe 

 further north than Guernsey, so that its occurrence in Alderney 

 is of the greatest interest, especially to French botanists, for 

 there seems now every probability that the plant will be found 

 on the cliffs of La Hague, just opposite. 



The best additions among Flowering Plants are Orchis 

 morio, June us capitatus, und Lemna irlsulca. The previous 

 records for the last species within the Sarnian area were ancient 

 and somewhat nebulous. Many notes which I have collected 

 on the Alderney rarities must remain over for the present ; but 

 one or two maybe given here. Calamintha cllnopodium occurs 

 thinly scattered in a grass field behind Essex House, about a 

 quarter of a mile distant from the Rochers station recorded in 

 the Flora. It is good to have two localities for this rare 

 species. One gigantic plant of SHene conica which I noticed 

 in 1902 at Longy, among many tall ones, measured twenty-one 

 inches in height above the ground, — probably a record size for 

 this species ! A single specimen of the beautiful Vetch Vicia 

 varia was found on the cliffs last summer, so that possibly some 

 day it may become established here. Filago germanica and 

 Sayina nodosa, which I had not seen when the Flora was 

 written, I have since found : the former in good quantity on
